Cut the apricots into small pieces and place in a bowl. Add the amaretto and sugar and mix everything well. Now put the apricots in the fridge for an hour.
Whip the cream until stiff and add the vanilla sugar. Fold the sour cream into the cream.
Take the apricots out of the fridge and place in a small baking dish. I used a 27 x 18 cm form. Pour the cream and sour cream mixture over it. Crumble the shortbread biscuits and spread them on the cream. Put everything in the fridge again for an hour and then serve.
